EUK 134 0.1%

Product Overview

Experience the "perpetual motion machine" of skincare antioxidants with The Ordinary EUK 134 0.1%. This rare and highly sophisticated molecule is a self-regenerating powerhouse designed to provide around-the-clock defense against oxidative stress. Unlike standard antioxidants that are "used up" once they neutralize a free radical, EUK 134™ mimics the activity of two natural enzymes found in your skin—superoxide dismutase and catalase—to continuously scavenge free radicals all day long. This water-free, oil-like serum targets dullness and lackluster skin tone, promoting a visibly radiant and healthy-looking complexion while shielding you from environmental aggressors.

Key Benefits

• Self-Regenerating Technology: Unlike other antioxidants, EUK 134™ doesn't degrade after neutralizing free radicals; it keeps working to protect your skin for longer.
• Mimics Natural Defense: Replicates the skin’s own antioxidant enzymes to provide biological-grade protection.
• Boosts Radiance: Actively transforms "tired" or dull complexions into a glowing, vibrant state.
• Defends Against Pollution: Ideal for urban environments, protecting skin from smoke, smog, and environmental toxins.
• High Potency: Formulated at an exceptionally high 0.1% concentration—most competitors use significantly less.
• Hydration Support: The anhydrous (water-free) base prevents trans-epidermal water loss, keeping skin feeling soft.
• Soothes Redness: Helps calm the visible effects of oxidative stress and environmental irritation.
• Low-Irritation Formula: Despite its high potency, it is suitable for all skin types, including sensitive skin.
• Advanced Anti-Aging: Prevents the breakdown of skin structural proteins caused by free radical damage.
• Non-Greasy Feel: While it has an oil-like texture, it absorbs smoothly into the skin without a heavy residue.

Key Ingredients and The Science Behind Them

• 0.1% EUK 134™ (Ethylbisiminomethylguaiacol Manganese Chloride): This is a synthetic molecule with a structure that allows it to behave like a natural antioxidant enzyme. It is particularly effective because it handles two types of harmful oxygen molecules simultaneously, preventing them from damaging the skin barrier. Because it is highly sensitive to acids, we have formulated it in a stable, water-free base.

How to Use

1. Timing: Use alone or after water-based serums, ideally in the morning (AM) to provide daytime protection.
2. Application: Apply a few drops to the face and neck. A small amount goes a long way.
3. Sequence: Apply after water-based products but before oils or heavy creams.
4. STRICT CONFLICTS: Do NOT use in the same routine as Direct Acids (AHAs/BHAs like Glycolic or Salicylic acid) or Pure Vitamin C (L-Ascorbic Acid). Strong acids will completely destroy the EUK 134™ molecule.
5. Note: The serum has a naturally dark, amber color. This is normal and does not stain the skin when blended out.

Who is it for?

• The Urban Skincare User: Essential for those living in cities with high pollution levels.
• Lackluster Skin: Anyone whose skin looks "gray" or tired from environmental exposure.
• Sensitive Skin: Those who need antioxidant support but find Vitamin C or Resveratrol too stimulating.
• Anti-Aging Minimalists: People looking for a one-drop solution to prevent future skin damage.

FAQ

Q: Why is the price so low if it's high potency?
A: At The Ordinary, we believe in transparent pricing. While EUK 134™ is an expensive and advanced molecule, we keep our margins fair to ensure effective clinical skincare is accessible to everyone.

Q: Can I use this with Niacinamide?
A: Yes! EUK 134™ and Niacinamide are a fantastic combination for brightening and protecting the skin in the same routine.

Q: Why can't I use it with Vitamin C?
A: Pure Vitamin C is highly acidic. EUK 134™ is extremely sensitive to acidic environments and will lose all its potency if it touches a low-pH product. Use Vitamin C in the PM and EUK in the AM to get the best of both worlds.

Q: Does it have a scent?
A: It is fragrance-free, but it has a very faint, naturally occurring clinical scent that is barely noticeable.

Q: Will it make my skin feel oily?
A: It feels like a very "dry" oil. It spreads easily and leaves a silky finish rather than a greasy one.
